Application lt .Tune 4, 1909. Serial No. 509,222.

To all whom 'it may concern:

Be it known that we, HENRY M. FRIESEN and HEINRICH H. NIKKEL, subjects of the King of Great Britain, residing at Altona, county of Lisgar, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Grain Shockers;4 and we do hereby declare that the following .is a full, clear, and exact'description of the invention, such as will enable others skilled in the art to which it appertains to make i and use the saine.

longitudinally reciprocable cradle mounted to have both verticaland inclined oscillatory movement relatively to its supporting frame,

-ineans for closing' and opening said cradle,

means for oscillating said cradle in a plane inclined to the horizontal, means for moving said cradle longitudinally, and means for oscillatiug said cradle in a vertical plane.

ln order to more clearly disclose the construction, operation and use of the invention, reference should be had to the accompanying drawings forming partof the present application. i Throughout .the several figures of the like reference characters desig; nate the' saine parts. f

In the drawings: Figure 1 is aplan view of the` shocker attachment complete, showing, in dotted lines, the cradle in position Fig. 2 i's a rear end position to receive-sheaves; Fig'. 3 is a detail side elevation of the mechanism for moving the shocker longitudinally of its frame; Figf, 4 is aV detail side elevation of the mechanism for rotating the cradle to shock depositing position;I Fig. 5 is an enside eleva-tion of the rack and pinion for moving the ciadle-longitudinally; Fig. 6 is a'n enlarged detail of the interinittent gears for oscillating the ci'adlein a plane erspectiveot the harvester vertical plane; Fig. 9 a side elevation of the catch for holding the cradle in closed position; and Fig. 10 is an enlarged fragmentary detail, showing the neutral clutch enlarged. l

A substantial wheeled-'framework of any desired construction may be used for supporting the several Working parts of the attachment.y This framework may be either rigidly or detachably connected to the usual harvester frame in any of the usual and Well known ways of connecting similar attachments to harvester frames.

In the preferred form of the attachment, the frame comprises longitudinal rods or bars l, connected near one end by a transverse beam 2 and braces or struts 3 to hold the bars 1 rigid and maintain their relative positions to one another.

A transverse rod 4 is revolubly mounted in blocks 5, slidably mounted on the bars 1 and extending through this rod at an angle to its longitudinal axis, is revolubly mounted a'post 6, provided on its lower end with an intermittent bevel pinion 7 for revolving the post. To the upper part of the post are connected two 'coperating cradle members 8 and 9, adapted to receive betWeen't-hem sheaves'of grain from a harvester table. The intermittent pinion 7 is adapted to mesh with and be intermittently ond intermittent pinion 10. The pinion 7 is provided with two diametrically opposite concave toothless portions 7, adapted to fit, in' sliding contact, with the toothless portion of the pinion 10. As shown in Fig. 6,"tliis sliding fit of the two toothless surfaces will act toprevent rotation of the pinion 7 ,while at the same time pinion 10. The toothed section of the pinion 10 is provided with the same number of gear teeth as each of the two toothed sections of half rotation to every completerotation of the gear 10 and the gear 7 will be interrupted atthe end of its rst halt` rotation and remain stationary during a half rotation of the gear 10 at the end of which time both gears 7 and 10 will move through another half rotation. At the end of such partial rotation, the toothless portions will be in contact, and rotation of the gear 7 will be temporarilyinterrupted. The intermittent gear 10 is secured to the end of a stub shaft v1l, to the upper end of which is fastened a a pinion 13' secured to a stub shaft 14 passed Patented Feb. 21, ilgil.

driven by a secthe gear 7, thus the gear 7 will make a one pinion 12, adapted to be intermeshedl with through the beam 2and carrying oniitsopposite end the bevelV gear driven `by a bevel pinion 16 on mounted in hangers depending from the un,- l meut gears 26 and 27,

der side of the beam 2. The opposite end of' c the shaft 17 has secured thereto a bevel pinf driver. 20

ion 148, adapted to mesh with and be driven by a smaller bevel pinion 19 on a continuously driven shaft 20, which maybe Operated from the harvester mechanism in any well known manner, as usual. The coperation of the toothless vsections of the intermediate gears 7 and 10 acts as a safeguard against excessive rotary movement of the cradlev in either direction. The instantand duration of engagement of gears 12 and 13, and the-duration of rotation of gear 13, are

.all dependent on the manual operation of the driver is either a little early If the or a little late in suchoperation, considerable dainage might result, except for such coperating toothless sections.

It is desired, of course, to drive the shaft 17 only intermittently from the shaft 20, so

that'the cradle and the shaft 4 may be partially loaded. For this purpose, the gear 18 is provided with a hub that ts over the end `of the shaftI 17 and revolves .freely thereon.

" ably keyed on the This hub is provided with a clutch face 2l, adapted to eoperate with a ,clutch 22 slidshaft 17 and provided with a collar adapted to be engaged by the fork of an operating lever 23, pivotally mounted on the beam' 2 and operable by the harvester driver throu h suitable connections 24.4 Between the clutch 22 and a collar on the shaft 17, is interposed a coil spring 25, which acts normally to keep the clutch '17 may and sleeve in engagement. Thus the shaft be .driven from the shaft 20 at any time, and for any desired length of time. When the cradle is in position to be loaded, the gears 12 and 13 vwill be in mesh. Consequently, rotation of the shaft 17, at such,

time, will effect rotationvofthe post G and attached cradle 8 and 9, in a plane inclined to the horizontal.

' horizontal, position In order to deposit the shock from the cradle,fit is necessary, lof course, to swing the cradle, after rotation, from its vnormal toA a vertical position. Such movement of the cradle is. effected by partial rotation of the rod 4 on which `it is mounted. In order to, so partially `rotate the rod'4, a quadrant orsegment gear 26 is secured to one end of the rod'4. This quad- -rant gear meshes with and -is actuated by a similar segment gear 27, secured to a"stub shaft mounted in the framework of the attachment. This second segment gear 27 may be operated by a suitable hand lever 28,

and a chain of link rods and connecting levers, as shown in Fig. 4, the lever being placed near the seat of the harvester driver.

rotated and moved -only when it is.

the shaft 17 revolubly and When the cradle has been rotated-in plane inclined to the horizontal` by gears 12 13, and rotated vertically through segit should be moved longitudinally towardthe rear of its sup porting frame to deposit the shock. Such longitudinal movement is effected by coperating racks and pinions operated from a i the frame, parallel to and adjacent the shaft 17. It is driven from the shaft17 by intermeshing gears 30 and 31, on the shafts 17 and 29 respectively. the shaft 29 are provided with pinions 32, adapted to engage and operate interiorly toothed yoke-shaped racks 33, which are loosely journaled on the opposite ends of the rod 4 on which the cradle 8 yand 9 is 1nounted. Consequently, rotation of the shaft 29 will act to drive the racks 33, thus moving the rod 4 and cradle 8 and the cradle has reached the rearward limitof its movement and the shock has been deposited, as will be hereinafterdisclosed, it is lnecessary to return the cradle to its original position for reloading. of this return movement is a longitudinal movement in a direction opposite to that last effected. Both longitudinal movements are effected by pinions 32 and racks 33. Consequently, means must be providedfor maintaining the interineshing of the pinions `32 and racks 33 during both'longitudinal movements. 1n order to accomplish this result, each of the rack yokes 33 has been provided with a flange 34 extending along its upper edge and adaptedto be engaged by a lsmall roller 35 carried by a hanger 3G dropped from the framework of the attachment and having its lower end journaled upon the `32 is rotated to drive the racks 33' rearwardly, it will engage the lower face of the rack. Niththe parts in this position, the roller 35 will travel in vcontact with the under face of the flange 34, thus maintaining -the intermesli of they pinion with the lower face of the yoke rack. When the pinion reaches the forward end of the yoke rack, it will act to draw the rack slightly downward. At this instant, the forward end of the flange 34 reaches the roller 35, andthe flange drops below the roller 35. The continued rotation of the pinion'32 starts forward movement of the yoke rack and the intermesh between the pinion -and upper side lof therack yokev is maintained by en-A gagement between 'the roller 35 and the upper f-ace of the flange 34. f .v

The yieldingconnection between each ybke rack 33' andthe rod 4, comprises a spring-pressed neutral clutch member 37,

slidably mounted on the'rod 4, and a copeountershaft 29, extending transversely of 9 lonv gitudinally of its supporting frame. /Vhen erating clutch face formed on the arm 38 of The opposite ends of The first step shaft 29. As the pinion shoulder 45 and mounted the Vyoke rack. Normally, the friction grip between the two clutchl facesjwillact to keep the vokcs raised, so that the pinion 32 will be in mesh with the lower set of rack teeth ot' the yoke rack, so that the roller will pass under the flange 34 and maintain such engagement. Asthe pinion reaches the forward end of the yoke rack, it will draw the yoke 'rack downward, overcoming the frictional engagement between the clutch faces. As the pinion engages the rack teeth of the upper edge of the yoke rack, the spring-actimted clutch 37 will' again become operative. j

The complete cradle comprises a lower rigid cradle section 8 and an upper coperating pivotally mounted cradle section 9.v lVhen the cradle is in position to receive sheaves from the usual table of the harvester the section 9 will be raised, as shown in Fig.

v2. This is the normal position of the cradle. In' order'to maintain the upper sect1on nor- 4mally raised,

it is provided with a projecting arm, lwhich is connected with the cradle post by a spring 39. When the cradle has received a sufficient number of sheaves for a shock, it will be necessary to draw down the upper member 9, of course. This may be done automatically as the cradle is rotated in a plane inclined to the horizontal. The automatic closing device comprises a segment gear 40, mounted about or adjacent the lower part of the cradle post 6,a bevel pinion 4l secured to the lower cradle member adapted to mesh with and be driven by the segment gear and provided with a spool hub 42, and a flexible member 43 having its opposite ends j connected respectively to the cradle section 9 and the spool hub 42. As the cradle is rotated in a plane inclined to the horizontal, the bevel pinion 41 will engage the segment gear 40 and wind up the flexible connection 48, the pinion and segment gear being so proportioned that, as'the horizontal movement of the cradle is completed, the. winding of the member 43 will have completely lowered' the upper cradle member so that the cradle may be turned vertically without fear of dropping the sheaves. At this point, thepinion 4l leaves the segment4 gear 40. In order to prevent accidental opening of the cradle and consequent dropping of the sheaves, in subsequent movements of the cradle, a catch or holding device has been provided to secure the upper cradle section in its lowered or operative position. This .catch comprises a pivoted, spring pressed plate 44, provided with a on an oiiset of the lateral arm 46. This catch liesdirectly in the upward path of movement of the 'projecting arm of the cradle section 9. As the arm of the section moves upward, it will engage the lower beveled end of the plate 44, rock it on its pivot, and be seated on the shoulder 45. The plate 44 is so proportioned and positioned that its lower end which carries the shoulder 45 will normally project slightly into the upward path ot' movement of the arm projecting from the upper cradle section 9. In this wav, the upper cradle section 9 will be caught and held in operative position as soon as it has been closed by wmding upof the member 43. As the cradle reaches the rear ot the supporting frame, it will be necessary, of course, to provide means for tripping the plate 44 to free the upper cradle section to the action of the' spring 39, so that the cradle may be swung open to deposit the shock. The tripping device comprises a rod 47, pivoted to the arm 46 between its end and the offset. The rod 47 has an upturned portion at one end adapted to engage and swing the plate 44 to coune teract the spring, so that its shoulder 45 will be disengaged from the arm of the cradle section 9. lVhen near the end of the frame member l, the rod 4T will be engaged by a stop 49 projecting from the member '1. As soon as the rod strikes the stop, it will swing the plate 44, which will free the cradlel member 9 tothe action of its spring' 39, so that the cradle will be opened and the shock deposited..

In order to assist in rotation of the cradle, an inclined arcuate supporting rail 50 has been secured to the frame of the attachment, in such position as to be adjacent the lower side of the rigid cradle section. The `y rigid cradle section is provided with an `'anti-friction bearing 51, adapted to travel over the face of the supporting rail 50. Y.

Anti-friction rollers 48 may be .provided on the end of the arm 46, and on the outer end of the lower cradle section to travel on the longitudinal frame members l and so aid in supporting the cradlethereon.

the first or angular,

moved longitudinally to deposit the shock` it is necessary, of course, to prevent delivery ot-sheaves from the harvester table. Consequently. a retaining fork has been provided which copcrates with the sbeaf table. A beam 53 extends' from the harvester frame above the usual harvester table, and has piv 'otally mounted therein a rock sha tt 54, provided with a plurality ottcurved retaining fork tines 55. mally, in operative position bv a spring 5G, connected at its opposite endfsI respectively to the rock shaft 54 and the beam A catch v57 is pivoted to the beam 58, and is adapted to engage a pin or stud 58 on an arm 59 projecting from the rock shaft 54, to

f hold the tines 55in raised position. A' cord or light rope is connected to this catch for disengaging the catch from the pin 58, when desired. A rope, cable, or other device (30 is connected to the upper end of the arm 59,

These tines are held, norso that the shaft 54 may be rocked to move the tmes 55 to moperativelposition to allow the sheaves to pass from the harvester table.

Vlf desired, the cable 60 may be so connected to the cradle operating mechanism asi to raise the tines 55. when the cradle is moved to position to receive the sheaves, and allow lowering of the tines as the cradle 'begins to turn, after it is loaded. Of course, its operation may independently of the operation of the other parts of the machine, in any convenient and well known manner.

f from the shaft 20. From the shaft 17 the train of gears 16, 15, operate to swing or revolve the cradle post and cradle angularly about the axis of the post 6. As the cradle swings,\th.g]pinion 41 will be engaged and operated by t e segmentgear 40 and the liexible member 43 will be wound on the spool 42, drawing do-wn the upper cradle member 9 to closed position. As the cradle member 9 is drawn -completely down, its projecting arm slides onto the shoulder/45'of thecatch plate 44, thus,hold ing the cradle closed. As soon as thesettwo movements have been completed, the harvester driverwill swing the lever 28 rearwardly, thereby rocking the shaft 4 about its longitudinal axis and so disengaging the gears 12 and 13 and rotating the 4closed cradle vertically. The yielding connection between the shaft 4 and the yoke racks 33 will forc'ethe lower racks of the yoke racks into engagement with the pinions 32 on the countershaft 29, which is driven from the shaft 17 through the gears 30 and 31. As soon as the pinions 32 engage the lower racks of the yoke racks 33, the yoke rac-ks will be forced rearwardly, carrying with them the shaft 4 and its cradle. The gears 30 and 31 are so proportioned that the cradle will be moved rearwardly at the same rate that vthe v harvester and shock attachment move orward, thus keeping the cradle pnctically stationary relatively to the ground over winch the machine travels. As the cradle approaches the rear of the shocker frame,

-6-0 the end of the pivoted bar 47 will engage the stop 49 and trip the catch plate 44, freeing the cradle 9 to the action ofthe spring 39, and thus instantly opening the cradle to deposit the shock. At this moment, the pinions 32 will engage the forward end of the r yoke racks 33 and draw the same downward,

be effected by the harvester driver` 4clutch 22, and so 13, 12, 10 .and 7 will' so that the rollers will trave-l along the tops of the flanges 34 and maintain the intermesh of the pinions 32 and the upper racks of the yoke rack 33, thus returning the shaft 4 and cradle to the forward part of the frame. As the cradle reaches its forward limit, the rollers 35 will run lfrom the ends of the lflanges `34, and the pinions 32 will lie in the toothless portions at the rear ends of the yoke racks 33'. At this point, the 'segment gears 26 and 27 will be in mesh. Theharvester driver now operates the lever 2S, and so rotates the shaft 4 and swings the cradle to the cradle reaches its horizontal position, the gear 12 will mesli with the rotating gear 13, and thecradle will be rotated to position to receive sheaves from the harvester table. As soon as the open side ofthe cradle falls opposite the harvester table, the driver will pull the cord or cable 24 toV disengage the discontinue the drive of the shaft 17 -until the cradle has been again rotated. The entire operation will then be repeat-ed.

It is clear that changesimay be made in the construct-ion, arrangement and disposihorizontal position.` As soon as t-ion of the several parts of the invention,
